Abstract
An immersive video processing method according to the present invention includes: classifying view videos into a base video and an additional video; performing pruning for the view videos by referring to a result of the classification; generating an atlas based on a result of the pruning; determining a depth parameter of each view in the atlas; and encoding information indicating whether or not updating of the depth parameter is needed, based on whether or not the depth parameter of each view in the atlas is identical as in a previous atlas.
Claims10
A method for processing an immersive video, the method comprising:
- classifying view videos into a base video and an additional video;
- performing pruning for the view videos based on the classification;
- generating an atlas based on residual view videos resulting from the pruning;
- determining depth parameters of each of views;
- and
- determining a pixel value in the atlas by using the depth parameters of a corresponding view,
- wherein the method further comprises encoding information indicating whether the depth parameters of at least one view is updated or not,
- wherein when the depth parameters of none of views are updated, the depth parameters of each of views are maintained as the same as those used in a previous frame, and
- wherein when the depth parameters of at least one view are updated, depth parameter information indicating updated depth parameters of the at least one view is further encoded into a bitstream.
A method for synthesizing an immersive video, the method comprising:
- decoding an atlas;
- obtaining depth parameters of each of views;
- and
- obtaining a depth of a restored pixel in the atlas by using the depth parameters of a corresponding view,
- wherein the method further comprises determining whether the depth parameters of at least one view is to be updated or not,
- wherein when it is determined not to update the depth parameters, the depth parameters of the each of views are maintained as the same as those used in a previous frame, and
- wherein when it is determined to update the depth parameters, the depth parameters of the at least one view are updated by depth parameter information signaled for the at least one view.
